Carbon fiber is an inorganic polymer fiber obtained from organic fibers such as polyacrylonitrile, pitch, viscose, etc., which are carbonized to form a carbon backbone structure in a high temperature environment. Due to its excellent mechanical properties, carbon fiber Carbon Fiber Cloth
is known as the "king of new materials" and "black gold" in the 21st century. Carbon fiber can be combined with resin, metal, ceramics, etc. to form advanced carbon fiber composite materials, which are widely used in rockets, large planes, ships, wind power, photovoltaics, hydrogen storage tanks, golf clubs, and badminton rackets. Data show that in 2021, China's total carbon fiber demand will be 62,379 tons, a year-on-year increase of 27.7%. Among them, the supply of domestic glass fibres
was 29,250 tons, accounting for 46.9% of the total demand. Since the end of 2021, a number of companies have put into operation carbon fiber 10,000-ton capacity expansion projects.
Jin Liang, secretary of the board of Zhongfu Shenying, introduced that the company's first 10,000-ton project expanded in Xining, Qinghai will be put into operation in September 2021; the second 14,000-ton project has started construction and is expected to be put into operation by the end of this year. Guangwei Composites is the earliest mass-produced carbon fiber enterprise in my country. The company's business covers polypropylene fiber mesh
, Glass fiber strands
, carbon fiber and various downstream composite materials. According to the data, the planned production capacity of Guangwei carbon fiber project in Inner Mongolia is 10,000 tons, and it will be put into production before the end of this year.
The major engineering project in Shanghai - Shanghai Petrochemical's "24,000 tons/year raw silk, 12,000 tons/year 48K large tow carbon fiber" project is accelerating the resumption of work and production, and the project is scheduled to be completed in 2024. Lin Gang, a carbon fiber expert and general manager of Guangzhou Saio Carbon Fiber Technology Co., Ltd., believes that 2021 to 2022 is a strategic opportunity period for the high modulus Carbon fiber cloth
industry. China has built an industrial foundation for industrial application of carbon fiber, cultivated a number of related enterprises, and most of the technologies have reached a high level. The above-mentioned expanded production capacity will be gradually released in the next few years, which will alleviate the contradiction between supply and demand in the industry, and lay the foundation for the era of large tow and low cost for China's carbon fiber industry.
